2.地图浏览模块
该模块主要包括地图工具、滚动条，状态条、鹰眼图、内容视图等。其中地图工具可以实现放大、缩小、中心放大、中心缩小、全景视图、漫游、要素选择和取消、空间查询等具体功能。 a.地图工具
实现工具栏中的控件，比如加载地图文件、添加地图图层、地图显示、漫游功能、中心缩放、放大缩小等功能。 具体代码如下： private void OpenNewDocument_Click(object sender, EventArgs e) { ICommand command = new OpenNewMapDocument(m_controlsSynchronizer); ITool tool = command as ITool; command.OnCreate(m_mapControl.Object); command.OnClick(); }

private void ZoomOut_Click(object sender, EventArgs e) { ICommand command = new ZoomOut(); command.OnCreate(m_mapControl.Object); ITool tool = command as ITool; axMapControl1.CurrentTool = tool; } private void FixedZoomIn_Click(object sender, EventArgs e) { ICommand command = new FixedZoomIn(); command.OnCreate(m_mapControl.Object); command.OnClick(); } private void FixedZoomOut_Click(object sender, EventArgs e) { ICommand command = new FixedZoomOut(); command.OnCreate(m_mapControl.Object); command.OnClick(); } b.状态栏 在设计视图中，点击窗体中的状态栏，在其属性面板中找到“ Items ”项，单击其右边的按钮，在下拉框中选择“ StatusLabel ”，单击“添加按钮”，依次添加四个 StatusLabel ，依次修改属性参数如下表所示：
设置好之后如下图所示：
首先添加 axToolbarControl1 的 OnMouseMove 事件 在其事件响应函数代码如下： Private void axToolbarControl1_OnMouseMove(object IToolbarControlEvents_OnMouseMoveEvent e) {
// 取得鼠标所在工具的索引号
int index = axToolbarControl1.HitTest(e.x, e.y, false);
